1. Penn Plax Cascade Canister Aquarium Filter

Something that we really like about this filter, is that it is very simple to us. The Penn Plax Filter can be put together and started up in just a matter of minutes, something that is made even easier with the self-priming button that comes included. It also features easy to use clamps that make setting it up easy, and it also features adjustable flow rate valves so you can get things just right.

We really like the fact that this filter combines mechanical, biological, and chemical filtering to produce very clean water in a short amount of time. The combination of bio floss, bio sponges, activated carbon, and other forms of media all work together to remove particulate matter, fish waste, extra food, toxins, nitrates, discoloration, ammonia, and all other unwanted compounds from your aquarium.

This aquarium filter is great for medium sized fish tanks, that being about 80 gallons, because it can pump out over 185 gallons per hour. That pumping power combined with the big filter trays and advanced cleaning techniques ensures crystal clear water every time.

It’s really convenient because you can reduce the flow rate without actually reducing the amount of filtration that occurs, that being because up to 50 percent of the water will get re-filtered instantly.

Of course another great feature of the AquaClear Power Filter is that it combines mechanical, biological, and chemical filtration to provide for some really clean water indeed. It features a bio-max chemical filter to remove chemicals.

It also features an AquaClear carbon filter, as well as a foma insert to catch debris and particulate matter. The foam is also great because it provides a home for healthy bacteria to grow on, thus increasing the vitality of your aquarium even more.

We also really like the fact that this filter is not very expensive to buy or to maintain. Plus it is also very easy to clean and maintain, taking minimal effort to keep it in top notch condition. Perhaps one of the best parts about it is that this filter makes the water pass through the filters for 6 times longer than most other filters, thus providing for a really intense filtering session.

Perhaps the best feature about this particular aquarium filter is that it will work with both fresh and saltwater aquariums, making it very versatile indeed.

We also really like the super-strong motor that comes with the Fluval because it has the ability to maintain a really strong flow rate even when the filter hasn’t been maintained for a while. This motor has some serious HP and is sure to last for a very long time.

Another great feature of the Fluval Filter is that it is very easy to set up, connect to your tank, and get going. This thing was designed with simplicity and user-friendliness in mind, something that everyone can appreciate.

And the final 2 stages consist of a bio screen and bio nodes which gives good bacteria a place to grow, those bacteria working to clean your fish tank even more.

We are really impressed by the fact that the water stays in the filter for quite a long period of time, thus providing for optimal cleanliness. Not to mention that the flow rate can be adjusted, and when the rate is low, up to 50 percent of the water gets re-filtered to ensure that it truly is clean and ready for your fish.

What Is An Aquarium Filter And What Does It Do

Simply put, an aquarium filter is a device that you require if you have a planted aquarium or one with fish in it. It filters out harmful compounds in the water which may damage or kill the fish and other aquatic life in your aquarium by taking in water, passing it through a specific set of filters, and spitting out clean water into the tank.

The best aquarium filters will be able to remove debris, fish waste, extra food, chemical such as ammonia and nitrates, they should aerate the water with oxygen, and they should be able to grow bacteria in order to remove foul odors, discoloration, and other unwanted things from the water. These things are absolutely necessary if you have any hopes of maintaining a healthy underwater environment.

Different Types Of Aquarium Filters

There are a few different kinds of aquarium filters that you should know about. Now there are 2 main aspects to the filter that you need to be aware of. One of these aspects is the type of filtration that your filter can perform.

This refers to mechanical, biological, and chemical filtration, each of which cleans the water in a slightly different way. Mechanical filtration involves removing particulate matter and other debris. Biological filtration engages the nitrogen cycle to convert plant and fish waste into oxygen. And the chemical filtration aspect involves removing nitrates and ammonia from the water, among other things. Ideally the filter that you get should be able to do all of those things.

The other aspect of choosing a filter for your aquarium involves the style of filter that it is. The main types of filters that you can get include sponge or air driven filters, hang on the back filters, canister filters, under gravel filters, internal filters, fluidized bed filters, and wet/dry trickle filters. Let’s quickly talk about the most important ones.

Sponge

Sponge or air driven filters us an air pump to suck in water and pass it through a sponge which can perform biological and mechanical filtration. These are usually some of the cheapest models to get.

Hang On back

As the name implies, these filters are external filters that rest on the top or back of your aquarium. The good models can provide you with chemical, mechanical, and biological filtration in one. Many newer system have specialized bio wheels.

These models can be a little bit more expensive than the ones we previously discussed, plus they can be slightly louder too. However they also provide for better filtering capabilities too.

Canister

Canister filters are great because they provide all 3 kinds of filtration in one great tool, that being said, their biological filtering capabilities are somewhat low. These are some of the most popular types of filters because they are very efficient and do a fantastic job with mechanical and biological filtering.

They are ideal for larger fish tanks and are also great for salt water tanks. This type of aquarium filter can be quite expensive.

Under Gravel

This type of filter rests under the substrate of your aquarium. They tend to be pretty cheap, but that is because they only provide for biological filtration.

They do help with mechanical filtration by pulling water through the gravel, however that is an indirect process. These filters are also good for providing your aquarium with aeration.

Internal

Internal filters are usually pretty small and lacking in power. However they are ideal for small aquariums due to their size, plus in a small aquarium they still provide for more than enough filtering power. These filters tend to be relatively inexpensive. However they are limited in their capabilities.

Trickle

This type of filter is very complex, not as common as the rest, and can be pretty expensive too. They are fantastic for salt water aquariums and they do a really good job at mechanical, biological, and chemical filtration.

They are great at what they do, but they take a lot of time, effort, and maintenance in terms of their setup.
